Abstract
A device (100) for processing a decoded audio signal (100) comprising a filter (102) for filtering the decoded audio signal to obtain a filtered audio signal (104) a time-spectral converter stage (106) for converting the decoded audio signal and the filtered audio signal into corresponding spectral representations each spectral representation having a plurality of subband signals a weighter (108) for performing a frequency selective weighting of the filtered audio signal by a multiplying subband signals by respective weighting coefficients to obtain a weighted filtered audio signal a subtracter (112) for performing a subband-wise subtraction between the weighted filtered audio signal and the spectral representation of the decoded audio signal and a spectral-time converter (114); for converting the result audio signal or a signal derived from the result audio signal into a time domain representation to obtain a processed decoded audio signal (116).
An apparatus (100) for generating spectral replacement values for an audio signal is provided. The apparatus (100) comprises a buffer unit (110) for storing previous spectral values relating to a previously received error-free audio frame. Moreover the apparatus (100) comprises a concealment frame generator (120) for generating the spectral replacement values when a current audio frame has not been received or is erroneous. The previously received error-free audio frame comprises filter information the filter information having associated a filter stability value indicating a stability of a prediction filter. The concealment frame generator (120) is adapted to generate the spectral replacement values based on the previous spectral values and based on the filter stability value.
